This comes as a surprise, even though there were reports that the Bengals and Jones had been talking.
Off the field, Jones' latest run-in with the law --he pleaded guilty to a misdemeanor charge of disorderly conduct in January -- will be reviewed by the NFL, which could impose a suspension now that he has signed with a team.
On the field, the lasting impression of Jones was getting beat on a double move by Texans wide receiver Andre Johnson for a 40-yard touchdown in last season's playoff loss.
So why are the Bengals re-signing Jones? In their mind, he is better than the other options available, like free agent Terence Newman from the Cowboys. Jones was actually solid in the regular season when he replaced injured Leon Hall for seven starts. According to Pro Football Focus, Jones allowed 16 receptions in eight games in 2011.
The Bengals have taken a proactive approach in addressing a cornerback group that has Hall coming off a season-ending Achilles injury and Nate Clements entering his 12th season. Cincinnati also signed Texans free agent Jason Allen and could draft another corner in the first round. The addition of Jones likely means the Bengals won't re-sign Kelly Jennings.
Jones, 28, has been repeatedly arrested during his NFL career. He missed the entire 2007 season with the first of two suspensions from the league.
The Tennessee Titans traded Jones to Dallas before the 2008 draft. An alcohol-related altercation with a bodyguard that the Cowboys assigned to him led to another six-game suspension.
He was out of the NFL for a year before the Bengals gave him the two-year deal in 2010.
